Taking on the role of Hong Seol, Oh Yeon Seo recently posted a photo on her Instagram page, letting fans take a sneak peek at her transformation. The star can be seen getting her hair done at the salon. She has poofy brunette hair just like the character's hairstyle in the original webtoon series. 'Cheese In the Trap' launched as a webtoon in 2010 and was remade into a drama last January.

Meanwhile, fans are anticipating the film adaptation scheduled to open in theaters this year, starring Park Hae Jin playing the leading male character Yoo Jung.

Looks wise...it's on the dot. Let's see whether she can carry the role. I loved Kim Go Eun in the drama version coz she seemed so real and relatable; even if she didn't look anything like the original character

She's an amazing actress,she will do a great job I'm sure of it.. I just wish they hadn't casted Park Hae Jin,I loved him in the drama but the whole cast has changed for the movie and idk it just feels weird...

I hope the movie will be good. CITT drama was perfect at the beginning and the casting was great too, it’s just that the PD and the scriptwriter screwed up the ending big time. While I loved Kim Go Eun’s portrayal of Hong Seol, I think Oh Yeon Seo will be able to pull Hong Seol off.
